Description

Den foreliggende oppfinnelse vedrører en filtreringspresse som i sin sluttende har en etterpressingsanordning som utfører den endelige pressing og som består av minst to pressvalsepar som angitt i innledningen til det etterfølgende selvstendige krav 1. The present invention relates to a filtering press which at its end has a post-pressing device which performs the final pressing and which consists of at least two pairs of press rollers as stated in the introduction to the subsequent independent claim 1.

I tidligere kjente filtreringspresser av dette slag, i hvis etterpressingsanordning det er anordnet et flertall pressvalsepar eller nip for forhøyelse av det endelige tørr-substansinnhold, har man kun kunnet fordele presskraften mellom pressnipene i et visst forhold fastlagt av den permanente konstruksjonen. Oppfinnelsen tar sikte på en videreutvikling av den omtalte f i 1 tr eringspresse . Filtreringspressen ifølge oppfinnelsen kjennetegnes ved at presskraftforholdet mellom valsene er regulerbart ved hjelp av en reguleringsanordning. Med oppfinnelsens hjelp kan man således innbyrdes regulere pressvalseparenes presskrefter eller nipkrefter, til og med under prøvekjøringer eller igangsettingskjøringer. Tidligere har man ikke i det hele tatt kunnet regulere disse presskrefters forhold, idet forholdet har alltid vært konstant. In previously known filter presses of this kind, in whose post-pressing device a plurality of press roller pairs or nips are arranged to increase the final dry substance content, it has only been possible to distribute the pressing force between the press nips in a certain ratio determined by the permanent construction. The invention aims at a further development of the mentioned f in 1 tr ringing press. The filtering press according to the invention is characterized by the fact that the pressure force ratio between the rollers can be adjusted by means of a control device. With the help of the invention, one can thus mutually regulate the pressing forces or nip forces of the press roller pairs, even during test runs or start-up runs. In the past, it has not been possible to regulate the relationship between these pressure forces at all, as the relationship has always been constant.

En fordelaktig utførelsesform av oppfinnelsen som angitt i karakteristikken til det etterfølgende, uselvstendige krav 2, er at reguleringsanordningen består av et flertall festepunkter for sylinderens ender, med hvis hjelp sylinderens, posisjon er regulerbar i massebanens lengderetning. Sylinderens posisjon kan derved grovreguleres før filtreringspressen startes. An advantageous embodiment of the invention as stated in the characteristic of the subsequent, independent claim 2, is that the regulation device consists of a plurality of attachment points for the ends of the cylinder, with the help of which the position of the cylinder can be regulated in the longitudinal direction of the mass path. The position of the cylinder can thus be roughly adjusted before the filter press is started.

En annen utførelsesform av oppfinnelsen som angitt i det etterfølgende uselvstendige krav 3, er at reguleringsanordningen består av i massebanens lengderetning trinnløst, f.eks. ved hjelp av reguleringsskruer, regulerbare festepunkter for sylinderen. For eksempel leddmekanismer som kan forskyves ved hjelp av reguleringsskruer. Sylinderens posisjon kan dermed f inreguleres , til og med under filtreringspressens gang. Another embodiment of the invention, as stated in the following independent claim 3, is that the control device consists of steplessly in the longitudinal direction of the mass path, e.g. by means of adjusting screws, adjustable attachment points for the cylinder. For example, joint mechanisms that can be moved using adjusting screws. The position of the cylinder can thus be regulated, even while the filter press is running.

En tredje utførelsesform av oppfinnelsen ifølge det etter-følgende uselvstendige krav 4, er karakterisert ved at reguleringsanordningen består av i massebanens lengderetning bevegelige sleider, i hvilke sylinderens ender er festet. Dette er en alternativ eller en kombinert utførelsesform i forhold til de foregående utførelsesformer. A third embodiment of the invention according to the following independent claim 4 is characterized in that the control device consists of slides movable in the longitudinal direction of the mass path, in which the ends of the cylinder are fixed. This is an alternative or a combined embodiment in relation to the preceding embodiments.

Oppfinnelsen skal i det følgende beskrives ved hjelp av et eksempel med henvisning til den etterfølgende tegning, hvor fig. 1 forestiller en filtreringspresse sett fra siden, In the following, the invention will be described by means of an example with reference to the subsequent drawing, where fig. 1 depicts a filter press seen from the side,

fig. 2 viser den i filtreringspressens sluttende forekommende etterpressingsanordning i større målestokk. fig. 2 shows the post-pressing device found in the filter press on a larger scale.

Etterpressingsanordningen i filtreringspressens sluttende utfører den endelige pressingen for forhøyelse av tørr-substansinnholdet. Etterpressingsanordningen består av to pressvalsepar 1,2 mellom hvilke valser 3,4,5,6 de til pressen hørende wirer 7,8, løper og hvor massen 9 mellom wirene blir presset på grunn av en på de øvre valser 3,5 innvirkende presskraft F frembragt ved hjelp av en trykksylinder 10. Presskraftforholdet F1/F2 er ved hjelp av reguleringsanordningen 11,12 regulerbare i de retninger som pilene 13,14 angir. Reguleringsanordningen 11, 12 utgjøres av i massebanens retning trinnløst forskyvbare reguleringsskruer 15,16. Forholdet mellom pressvalseparenes 3,4 og 5,6 presskrefter F^ og F2 kan hermed reguleres til og med i forbindelse med pågående prøvekjøringer eller igangkjøringer. I samtlige tidligere kjente filtreringspresser har dette forhold mellom presskreftene alltid vært konstant. The post-pressing device at the end of the filter press performs the final pressing to increase the dry matter content. The post-pressing device consists of two press roller pairs 1,2 between which rollers 3,4,5,6 the wires 7,8 belonging to the press run and where the mass 9 between the wires is pressed due to a pressing force F acting on the upper rollers 3,5 produced by means of a pressure cylinder 10. The pressure force ratio F1/F2 can be adjusted by means of the regulation device 11,12 in the directions indicated by the arrows 13,14. The regulating device 11, 12 consists of regulating screws 15, 16 that can be continuously moved in the direction of the mass path. The ratio between the 3.4 and 5.6 pressing forces F^ and F2 of the press roller pairs can be regulated even in connection with ongoing test runs or commissioning. In all previously known filtration presses, this ratio between the pressing forces has always been constant.

Det er klart for en fagmann i bransjen at oppfinnelsen ikke er begrenset til det ovenfor viste eksempel, idet den kan varieres innen rammen for de etterfølgende patentkrav. Således kan forholdet mellom presskreftene reguleres f.eks. ved hjelp av to pressende sylindre, hvilkes presstrykk er regulerbart i likhet med i og for seg kjent teknikk. It is clear to a person skilled in the industry that the invention is not limited to the example shown above, as it can be varied within the scope of the subsequent patent claims. Thus, the ratio between the pressure forces can be regulated, e.g. by means of two pressing cylinders, the pressing pressure of which is adjustable in the same way as in per se known technology.
